SPECIFICATION forming part of LettersIPatent No. 276,198, dated April24, 1883.

Application filed January 27, 1883. (No model.)

To all whom it may concern:

Be it known that I, SETH H. SMITH, a citizen of the United States,residing at Delta, in the county of Fulton and State of Ohio, haveinvented a new and useful Machine for (Jutting Wooden Plates, of whichthe following is a specification, reference being had to theaccompanying drawings.

This invention relates to a machine for cutting continuously from ablock of wood concavo-convex shells, plates, or dishes, serving aspackages for butter, berries, and for other purposes; and my inventionconsists in certain improvements in the construction of the saidmachine, which will be hereinafter fully described, and particularlypointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective view of myimproved machine. Fig. 2 is a side view of the same. Fig. 3 is a frontview. Fig. 4 is a top plan. Fig. 5 is a longitudinal vertical sectionalview. Fig. 6 is a detail view in perspective of the feed mechanism. Fig.7 is a detailview of the frontend of the follower, showing the mechanismfor holding the block of wood in position for operation. Fig. 8 is adetail view of the mechanism for connecting the feed-screw with thefollower, and Fig. 9is a detail view of the stop mechanism.

The same letters refer to the same parts in all the figures of thedrawings.

The frame of my improved machine consists essentially of a box ortrough, A, mounted or supported upon suitable legs or standards, B. Atthe front end of the box A bearings are provided for the transverse mainshaft (J, carrying a band-wheel, D, to which motion may be transmittedfrom any suitable motive power. The main shaft is provided in front ofthe box A with hubs or collars E E, to which acurved knife or cutter, F,is securely attached. One side of the box A has bearings for alongitudinal shaft, G,the front end of which has a bevel gear or pinion,H, engaging a like pinion, I, upon the end of the main shaft 0. J is ahub or collar secured upon the shaft G in rear of the pinion H, andhaving an arm, K, to which a straight radial knife or cutter, 'L, isbolted or otherwise secured. This cutter, when the shaft Grevolves,moves directly in front of and almost in contact with the frontend of the box A. A horizontal U-shaped bracket, M, is provided, forminga guard for the knife L.

N is a follower, sliding longitudinallyin the trough A. The saidfollowerconsists ofa box,

is pivoted a disk, 0, having an upwardly-projecting arm or lever, P, bymeans of which it may be oscillated upon its pivot. The front end of thebox has bearings for two laterallysliding arms or dogs, the outer endsof which have inwardly-turned sharp hooks Q, while the inner ends of thesaid dogs, which are denoted by letter R, are provided with pins S,extending through slots T in the front end of the box or follower andinto eccen trio slots U formed in the disk 0.

It will be seen that by turning the said disk the dogs S may be movedapart, so as to release, or together, so as to clamp and hold the blockof wood to be cut, which has been previously placed in the trough A, inwhich it should as nearly as possible fit. To receive the ends of thedogs S, slots or grooves V may be formed in the inner sides of the box.

The rear end of the follower-frame is provertically-sl ding half-nuts, XX, having pins Y Y, which engage eccentric slots Z Z in a plate, Apivoted to the end of the box or frame,and having an operating-handle, B0 is a feed-screw placed longitudinally in the trough A and journaled inthe rear end of the latter and in a bracket, D about centrally in thesame. The feed-screw passes through the slot W of the follower, betweenthe nuts XX, which, by the mechanism described, may be thrown intoengagement with or released from the feed-screw by simply operating thelever B The rear end of the feed-screw projects through the rear end ofthe trough Aand carries a ratchet-wheel, E of trough A, surrounding theend of the screw, is formed a collar, F upon which is journaled a hub, Ghaving arms H 1 the former of which carries a spring-pawl, J engagingthe ratchet-wheel E The arm 1 has a slot, K radial to the hub, in whicha Wrist-pin, L", is adjustable by means of athumb-nut or in any upon theinner side of the front endof which Upon the rear end vided with.a slot,W,in which are placed two the box'or trough A.

suitable manner. The pin L is connected by a pivoted rod, M with asimilar wrist-pin, N

radially adjustable in a slot, formed in a disk, P secured upon the rearend of the shaft G. It will thus be seen that when the latter revolvesthe disk P imparts an oscillating motion to the hub G2 and itsattachments, which in turn through the pawl J serves to revolve thefeed-screw, thereby feeding the follower forward in the box A. Thelength of the feed may be determined by adjusting the wrist-pins intheir respective slots.- To move the follower back it is only necessaryto disengage the halfnuts from the teed-screw by the mechanismdescribed.

The band-wheel D, which is loose upon the main shaft, may be thrown intogear with the latter by a clutch, Q sliding upon the said shalt. Theclutch is operated by a lever, R mounted upon a vertical pivotadjoining; the

box or trough A. The rear end of said lever rests upon a horizontal arm,S extending from a vertical shaft, T journaled to the side of The arm Sis provided with upwardly-projecting pins U between which the lever Brests. The-shaft T is provided at its upper end with aninwardly-projecting arm, V adapted to be engaged or struck by a stop, Wlongitudinallyadjustable upon the upperedge of the follower. This stopmay be set or adjusted so as to stop the machine when the followerreachesany desired point which may be previously determined. \Vhen thestud or stop W strikes 'the arm V it turns the shaft T thereby operatingthe lever R and throwing the clutch out of gear, thus stopping themachine.

The U-shaped bracket M, which has been hereinbefore described as forminga guard for the knife L, also performs an important function in formingone of the bearings for the main shaft 0, one end of which is journaledin a box, X upon the front arm of said U-shaped bracki t. Said arm,which is denoted by letter Y is connected by a brace, Z withoone of thesupports of the machine, thus holding themachine steady andwitho'uttrembling during operation.

The operation of. my improved machine will be readily understood fromthe foregoing description, taken in connection with the drawings heretoannexed. After moving the follower back, a block of wood of the propersize is placed in the trough A and clamped by the dogs 11. When themachine is started the block is fed to the knives or cutters, which areto be so arranged in relation to each other and to the feed that thefeed shall take place after the curved knife completes its passageacross the face of the block and before the knife L reaches the edge ofthe same, while the latter must nearly or quite complete its throwbefore the cutting-knife I comes into action. The function of the latteris to cut from the face of the block shells or concave-convex dishes,while the radial knife L, before each throw of the cutting-knife F,faces off the block, thus causing the knife F to cut always from theface of the block, and making all the shells out of exactly the samesize and shape. In cross-section the said shells are. naturallysegmental, while in longitudinal section their shape is governed by thatof the knife or cutter F. When the block has been cut up, or at anydesired point, the machine "is automatically stopped by the mechanismdescribed, and the butt-end may then be removed, the follower movedback, and a new block placed in position for operation.

I am aware that a clutch serving to conncct a drive-wheel to a shaft hasbeen arranged to be operated by the action of a follower upon the leverholding the said clutch, and such mechanism I do not broadly claim.

I claim as my invention and desire to secure by Letters Patentof theUnited States-- 1. A machine for cutting concavo-convex shellseoutinously from a block of wood, the same comprising in itsconstruction a revolving curved knife having both its ends attachcd tothedriving-shaft, and a facing-knife attached radially to a shaftlocated at an angle to the driving-shaft, substantially as set forth. i

- 2." In a machine for cutting concavo-comlex shells continuously from ablock of wood, the combination of a revolving curved knife having bothits ends attached to the drivingshaft, a facing-knife attached radiallyto a shaft located at an angle to the drivingshaft, and mechanism forfeeding a block inteumittingly to the said knives after the throw of thecutting-knife and before the throw of the facing-knife, substantially asset forth.

3. The combination of the frame-box having a collar upon its rear end,the feed-screw wrist-pins, and suitable operating mechanism,

substantially as and for the purpose set forth. 4. The combination ofthe main shaft, the

band-wheel mounted loosely upon the same and having a clutch, aclutch-collar sliding 'upon the shaft, a horizontal lever operating thesaid clutch-collar, a vertical shalthaving at its lower end an armsupporting the rear end of the lever between two vertical pins and atits upper end an inwardly-projecting arm, and the follower having alongitudinally-adjustable stop-stud, substantially as set forth.

In testimony that I claim theforegoing as my own I have hereto affixedmy signature in presence of two witnesses.
